Letting it age like a fine red wine?
Speaking of aging powder, my vintage H-4831 dates back from the 60's. I really like that powder.
Unfortunately, while doing a powder inventory, I saw that two cans of that old powder had gone bad. One can had the plastic cap eaten away, powder with brown stuff, bad smell. Another can showed some brown stuff, not as bad. I had to throw those two away. One can still smells and looks good.
This powder came in paper bags, was transferred to empty powder cans some time ago when the paper bags became brittle. I shot some really good groups with that powder in my .240 Wby.
Hurt my feeling to see it go after so long and it was in a climate controlled room.
Oh well...
